[libvirt] [PATCH] qemu: emit error when trying to update blkiotune group_name in qemuDomainChangeDiskLive

All rest of blkiotune parameters are not updatable through UpdateDeviceFlags API. https://bugzilla.redhat.com/show_bug.cgi?id=1601677 Signed-off-by: Katerina Koukiou <kkoukiou@redhat.com> --- The BZ was requesting to add support for updating the group_name for blkdeviotune here, though, all the rest of blkdeviotune elements are not updatable though UpdateDeviceFlags API. I think emmiting error and keeping all blkiodevtune parameters updatable in a consistent way is the right way to go. src/qemu/qemu_domain.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index de056272e8..0aa440e0b5 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -8791,6 +8791,9 @@ qemuDomainDiskChangeSupported(virDomainDiskDefPtr disk, CHECK_EQ(blkdeviotune.size_iops_sec, "blkdeviotune size_iops_sec", true); + CHECK_EQ(blkdeviotune.group_name, + "blkdeviotune group_name", + true); if (disk->serial && STRNEQ_NULLABLE(disk->serial, orig_disk->serial)) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, -- 2.17.1
